Is there any helpful hints or medicine/ pills to help prevent premature ejaculation?

Some. Counseling with a sex therapist or sexuality counselor may help. The therapist may recommend 1 or 2 techniques (stop-start and squeeze techniques). Some doctors prescribe antidepressants for premature or rapid ejaculation.
PE. I have tried a few strategies for my patients to help delay the pe. Using a condom with a numbing medication inside the condom desensitizes the the penis and will help to delay the time till ejaculation. Once the condom is off, the medication wears off in about 1/2 an hour. Another approach is using the side effect of a prescription medication such as zoloft or Paxil (paroxetine) to delay the ejaculation.
